Abstract

Embodiments of the invention are related to a system and method of controlling a display of image stream. The system may include a memory to store the image stream; the image stream may comprise a plurality of image frames. The system may further include a processor configured to execute the method. The moving image stream may be displayed to a user in an image stream display area of a screen and a frame rate control interface may be generated on a speed control area of the screen, such that the image stream display area is horizontally adjacent to the speed control area. An indication of a desired frame rate for displaying the image stream of the image frames may be received from the user, in that the frame rate may be selected according to a location of a pointing indicator in the speed control area.

Claims

1. A system for controlling a display of image stream, comprising:

a memory to store the image stream, the image stream comprising a plurality of image frames; and

a processor configured to;

display to a user the moving image stream in an image stream display area of a screen;

generate a frame rate control interface on a speed control area of the screen, such that the image stream display area is horizontally adjacent to the speed control area; and

receive from the user an indication of a desired frame rate for displaying the image stream of the image frames, the frame rate selected according to a location of a pointing indicator in the speed control area, wherein a movement of the pointing indicator inside the speed control area using a pointing device indicates a desired change in the frame rate.

2. The system of claim 1, wherein the processor is configured to display a stream advancement portion wherein the speed control area is for selecting a forward direction for displaying the stream of the image frames and the stream advancement portion is for selecting a backward speed for displaying the stream of the image frames.

3. The system of claim 1, wherein the processor is configured to:

receive from the user instructions to start or stop the stream of the image frames, the instructions indicated to the processor when the user clicks on the pointing device while the pointing indicator is positioned in the speed control area.

4. The system of claim 1, wherein the processor is configured to:

receive from the user instructions to stop the stream of the image frames such that a single frame is displayed in the image stream display area, when the user clicks the pointing device when the pointing indicator is at the speed control area; and

receive from the user instructions to scroll frames forward or backward from the single frame using the pointing device.

5. The system of claim 4, wherein the pointing device is a mouse and the instructions to scroll frames are received by detecting the rolling of a wheel of the mouse.

6. The system of claim 4, wherein the instructions to scroll frames are received by detecting a movement of the pointing indicator inside the speed control area.

7. The system of claim 1, wherein the screen comprises a portion displaying a scale showing a progress of the played stream of images from where the stream was last stopped.

8. The system of claim 1, wherein the processor is configured to:

receive from the user an instruction to accelerate the stream of the image frames, the instruction received when the user clicks and holds the pointing device in a clicked position for a period in which the stream of the image frames is to be accelerated.

9. A method of controlling a display of image stream, the method is executed by a processor, comprising:

displaying to a user the image stream in an image stream display area of a screen;

generating a frame rate control interface on a speed control area of the screen, such that the image stream display area is horizontally adjacent to the speed control area;

receiving from the user an indication of a desired frame rate for displaying the image stream, the frame rate selected according to a location of a pointing indicator in the speed control area; and

changing the frame rate according to the user'"'"'s indication.

10. The method of claim 9, wherein said pointing indicator is controlled by a pointing device and said indication selection does not require clicking on said pointing device.

11. The method of claim 9, comprising:

displaying a stream advancement portion wherein the speed control area is for selecting a forward direction for displaying the stream of the image frames and the stream advancement portion is for selecting a backward speed for displaying the stream of the image frames.

12. The method of claim 9, comprising:

receiving from the user instructions to start or stop the stream of the image frames, when the user clicks on a pointing device, which controls the pointing indicator, while the pointing indicator is positioned in the speed control area.

13. The method of claim 9, comprising:

receiving from the user instructions to stop the stream of the image frames such that a single frame is displayed in the image stream display area, when the user clicks on a pointing device, which controls the pointing indicator, when the pointing indicator is at the speed control area; and

receiving from the user instructions to scroll frames forward or backward from the single frame using the pointing device.

14. The method of claim 13, wherein the pointing device is a mouse and the instructions to scroll frames are received by detecting the rolling of a wheel of the mouse.

15. The method of claim 13, wherein the instructions to scroll frames are received by detecting a movement of the pointing indicator inside the speed control area.

16. The method of claim 9, wherein the screen comprises a portion displaying a scale showing a progress of the played stream of images from where the stream was last stopped.

17. A system for controlling a display of an image stream, comprising:

a storage unit to store the image stream, the image stream comprising image frames of at least one organ in a gastrointestinal tract captured by an imaging device included in an imaging capsule; and

a processor configured to;

display to a user the moving image stream on a screen;

determine a frame sequence of interest in the image stream, the frame sequence comprising at least two consecutive image frames from the image stream; and

provide an alert using a marker, the alert displayed to the user at a predefined time before the time of display of the first frame of said frame sequence.

18. The system of claim 17, wherein the frame sequence of interest includes candidate frames which depict a pathology candidate, and wherein the processor is configured to determine the frame sequence of interest by:

analyzing the image stream to locate the pathology candidate;

selecting at least one group of image frames showing the pathology candidate, such that the group defines a frame sequence of interest.

19. The system of claim 17, wherein the processor is configured to determine that a group of frames comprises a frame sequence of interest by:

selecting at least one group of consecutive frames associated with parameters larger than a threshold value, wherein the parameters are indicative of a speed or the movement of the capsule in the gastrointestinal tract.

20. A system for controlling a display of image stream, comprising:

a memory to store the image stream, the image stream comprising a plurality of image frames; and

a processor configured to;

display to a user the moving image stream in an image stream display area of a screen;

generate a frame rate control interface on a speed control area of the screen, such that the image stream display area is horizontally adjacent to the speed control area;

receive from the user an indication of a desired frame rate for displaying the image stream of the image frames, the frame rate selected according to a location of a pointing indicator in the speed control area, wherein the user changes the frame rate by moving the pointing indicator inside the speed control area using a pointing device;

determine a frame sequence of interest in the image stream, the frame sequence comprising at least two sequential image frames; and

generate an alert to the user by providing a predetermined indication, at a predefined time before the stream of image frames reaches the frame sequence of interest.
